Abstract:

Изучено влияние температуры и ультразвука на интенсивность извлечения антоцианового пигмента и пектиновых веществ. Показано, что спектры, описывающие интенсивность извлечения антоцианового пигмента черной смородины, имеют два максимума поглощения при длинах волн 510 и 280 нм. Установлено соответствие максимумов поглощения антоцианового пигмента длине волны 510 нм и пектиновых веществ, ассоциированных с полифенолами, длине волны 280 нм. Показано, что наиболее полно экстрагирование антоцианового пигмента и пектиновых веществ происходит при температуре 65 °С в течение 30 мин. Увеличение температу

Abstract:

The present paper compares the production of active substances in different subspecies of Achillea millefolium complex growing in the Czech Republic. Representatives of 7 subspecies of A. millefolium complex (A. setacea Waldst. et Kit., A. asplenifolia Vent., A. pratensis Saukel et Langer, A. collina Rchb., A. styriaca Saukel et Langer subsp. bohemica, A. millefolium subsp. millefolium, A. pannonica Scheele) and several natural hybrids of Achillea L. were collected from 75 natural habitats in different parts of the Czech Republic. Plants were cultivated to investigate plant growth and contents

Abstract:

Liquid waste of food industry enterprises contains various valuable organic substances of natural origin, which can be rationally used to obtain feed proteins. The problem of using valuable substances from food waste solves the problem of using biotechnological methods in order to use methods of accumulating biomass, enzymes, vitamins, etc. The biomass of unicellular microorganisms formed in the process of cultivation can be a raw material for obtaining feed additives and other biologically active substances.

Abstract:

AbstractThe target article suggests that taste is not based on the traditional four basic tastes, but rather is a continuum subserved by cross-fiber integration. This commentary describes evidence indicating that the traditional concept is valid, and that with suitable precautions, it is possible to match natural substances using mixtures representing fundamental tastes.

Abstract:

The article discusses the results of a study of the water solubility of natural sesquiterpene lactone arglabin, in particular, its ability to complex formation with complexing agents polyvinylpyrrolidone, the disodium salt of glycyrrhizic acid, magnesium carbonate. Mechanocomposites with polyvinylpyrrolidone and disodium salt of glycyrrhizic acid, which have increased water solubility, were obtained by the method of mechanochemical treatment of arglabin native. At the same time, the best result of dissolution in water is achieved by a two-hour treatment with polyvinylpyrrolidone and with disod

Abstract:

From the position of a cognitive approach the authors consider English deadjectival nouns, what involves identifying and describing knowledge domains represented by these language units in English language culture. The study is carried out on the material of deadjectival nouns, which are fixed in English dictionaries and selected by a continuous sampling method. A set of methods is used, the main of which are methods of conceptual-definitional and cognitive-matrix analysis. As a result of the study, it is revealed that English deadjectival nouns represent the structure of knowledge of an integ

Abstract:

The objective is to standardize the content of β-carotene – one of the principal active substances with sufficient hypolipidemic activity in the resultant original product. Search for natural biologically active substances having a hypolipidemic effect is one of the topical questions in modern pharmacy. Most of the research is carried out by means of isolating individual substances from the plant object. We propose to study a native phytocomplex obtained from pumpkin pulp – a dry extract of pumpkin pulp juice. The following materials and methods were used: laboratory-obtained dry extract of pu

Abstract:

The review summarizes studies on the detoxification effects of water-soluble humic substances (HS), which are products of the natural transformation of organic substances in soils and bottom sediments that serve as natural detoxifying agents in water solutions. The detoxifying effects of HS on microorganisms are quite complex: HS neutralize free pollutants (indirect bioeffects) and also stimulate the protective response of organisms (direct bioeffects). Prospects and potential problems of bioluminescent bacteria-based assay to monitor toxicity of solutions in the presence of HS are discussed.

Abstract:

These days, consumers are increasingly “nutritionally aware”. The trend of “clean label” is gaining momentum. Synthetic additives and preservatives, as well as natural ones, bearing the E symbol are more often perceived negatively. For this reason, substances of natural origin are sought tfor replacing them. Essential oils can be such substances. However, the wider use of essential oils in the food industry is severely limited. This is because these substances are highly sensitive to light, oxygen, and temperature. This creates problems with their processing and storage. In addition, they have
